Voltage (V). As you can see on the label is not explicitly stated voltage value (eg 11.1 v), and often can be found parameter S (in our marking indicates 3S). The value S is meant an amount LiPo cells connected in series to increase the voltage of the storage assembly. Since the rated voltage single LiPo cell is 3.7 volts (discharged voltage 3.3V, 4.2V charged), the voltage 3S battery is 3 * 3.7 = 11.1V. The label LiPo can meet both of these values. The number of cells in the battery assembly can be many:
7.4 = 2 x 3.7 In cell (2S); 3 = 11.1 x 3.7 in cells (3S); 4 cell = 14.8V x 3.7 in (4S); 18.5 = 5 cells x 3.7 in (5S); 22.2 B = 6 cells x 3.7 in (6S); 29.6 B = 8 cells x 3.7 in (8S); 37.0 B = 10 cells x 3.7 in (10S); 44.4 = 12 cells in x 3.7 in (12S).
Know that the lower value of the critical stress for 1S (one cell) battery is 3.3V, when the battery discharges below 3.3V in its chemical composition occur irreversible processes that will lead him into disrepair. balance plus So be aware of this and use the "golden rule", according to which it is not recommended to discharge the battery more than 80% of its stated capacity (mAh). This will protect balance plus your battery from premature failure.
Capacitance (C) is measured in mAh (milli-amp-hours). This means how much energy the battery can store. This capacity can be compared to the capacity of the fuel tank, the bigger it is, the longer it will run the engine. But keep in mind more than the capacity, the heavier and more expensive battery. Battery may be discharged very quickly, for example if it feeds power plant helicopter or multirotora or gradually, such as a glider. Current - electrical current. Measured balance plus in amperes. Mili Amp (mA) - it is 1/1000 Amp. Unit mAh (milli-amp-hours) indicates how current can provide consumers charged battery in one hour. For example, the battery capacity of 4000 mAh, it may provide balance plus power engine which uses four amperes for one hour. Or the video transmitter which consumes 250 mAh within 16 hours (4000mAch/250mAch = 16 h). The higher the input current, the faster the battery drain. Discharge current (C). In our example, this value is 30 (30C). But this is not Amps - it means that the current safe (for battery) discharge can be up to 30 values of its capacity. Just need to multiply the capacity of the battery 30, 4000 mAh * 30C = 120000 or 120 mAh A. Naturally, with such high current battery will discharge very quickly. Calculate how much time is enough capacity of our battery is also easy. At a discharge current balance plus of 2000 mAh, the battery will last for 2 hours, respectively, balance plus in one minute will consume 2000/60 = 33.3 mA. At a discharge current 30000 mA (or 30 A) per minute and consumes 500 mA, respectively, the battery capacity of 4000 mAh enough for 8 minutes balance plus (4000/500 balance plus = 8). In addition to these designations on the label of the battery can be found value Charge rate, Charge Capacity or Charge balance plus Speed. They all mean the same - the maximum current that can charge the battery. Represented as in the case of the discharge current, the letter (C) is considered similarly. If 2C, the charge current to the battery capacity will be 4000mAch 2 * 4000 = 8 Amps. These batteries are recognized balance plus across such comments as "the most fastidious, dangerous, unreliable and malozhivuschie", but despite balance plus all these drawbacks, the use of these batteries in the model airplane balance plus world is growing rapidly, as they are unbeaten record specific (by weight) of energy, as well as capable of giving large discharge currents. So that in models with high-voltage installations balance plus that batteries are virtually no alternatives yet.
When charging LiPo charge them only special charger for LiPo and only under supervision. In the case of some internal damage during charging can occur spontaneous combustion and fire. Never charge the battery balance plus without the balancer - devices, monitors and aligns the voltage on each "bank" in the series connected battery. For devices such as iMax B6, GTPower A6 and the like, having a built-in balancer and the choice of methods of charging, always choose Balance Charge balance plus mode instead of just LiPo Charge. The latter is not balanced and does not control each of the cans. To use the charge current of no more than 1C, if you are on the field, and about 0.5-0.7S at home. According to some, the slower charge will prolong battery life. Addition, some new types of batteries like Hyperion G3 admit charge currents balance plus up to 5C. In this case we can recommend such a charge in the field and at home - 2-3C will be enough though 1C home will not make worse When setting the escapement (ESC) always adjust its mode cutoff LiPo. When selecting NiMh it shuts off the power of the engine vovr
